Mounting outboard motor
EWM02500
WARNING
Improper mounting of the outboard mo-
tor could result in hazardous condi-
tions such as poor handling, loss of
control, or fire hazards.
Because the outboard motor is very
heavy, special equipment and training
is required to mount it safely.
Your dealer or other person experienced in
proper rigging should mount the outboard
motor using correct equipment and complete
rigging instructions. For further information,
see page 47.

Remote control requirements
EWM01580
WARNING
If the engine starts in gear, the boat can
move suddenly and unexpectedly, pos-
sibly causing a collision or throwing
passengers overboard.
If the engine ever starts in gear, the
start-in-gear protection device is not
working correctly and you should dis-
continue using the outboard. Contact
your Yamaha dealer.
The remote control unit must be equipped
with a start-in-gear protection device(s). This
device prevents the engine from starting un-
less it is in neutral.
